"Diminished reasoning" would encompass making silly claims like the red circles on the TSBD windows were some type of signal to LBJ. A laughable, tin foil hat claim easily debunked by newspaper articles explaining those circles years before the assassination. You are changing claims now. Previously you disputed that the authorities could link the rifle to Oswald. Now you are disputing that they could link it to the assassination. Let's see. A rifle is found hidden in the TSBD (or as you say "carefully hidden"). Witnesses confirm shots were fired from that building from a rifle. Shell casings are found by a window on the same floor. And the person linked to that rifle has fled the scene and been implicated in a murder of a police officer. He is also a known political kook. Now make a logical inference about the rifle. Even Inspector Clouseau could figure out it was likely the assassination weapon at that point.
PS...You shouldn't compare yourself to Inspector Clouseau .... Although I agree with you that even a dunce could be fooled by evidence presented by men with big shiny badges....
Previously you disputed that the authorities could link the rifle to Oswald. Now you are disputing that they could link it to the assassination. The authorities COULD link a model 91 / 38 carcano to Lee Oswald.... The BY photo shows Lee holding a carcano...
But they sure as hell could NOT link that carcano in the BY photo to the assassination... However maybe YOU can prove that the rifle in Lee's hands is the same rifle that was carefully hidden BENEATH pallets of books in the TSBD.... And Yes, Both Seymor Weitzman and Eugene Boone said they were able to see the rifle BENEATH the pallet when they got down on the floor and shined their flashlights BENEATH the pallet.....
